基于墨卡托海图的大圆航线设计

Study on Great Circle Route Planning Based on Mercator Chart

文章在比较大圆航线和恒向线差异的基础上,借助球面三角形的数学特性,设计了大圆航线,给航海人员航线设计提供了备用手段以节省航程,以期为同行提供参考。

Based on a contrast between the great circle route and the rhumb line, this article, combined with the mathematical characteristics of the spherical triangle, attempts to design the great circle route planning, which is expected to serve as an option for seamen to curtail the voyage.
